Composite samples were obtained by combining five sub-samples and separated into leaf leaf bladestem stem and sheathand dead material; the percentage of the total weight for each component was determined.
Soil chemical characteristics were as follows: The seeds were covered by using a locked disk harrow, and soil was compacted using a soil compaction roller. Average daily gain ADG was analyzed using multivariate repeated measures analysis according to Littell et al. These traits suggest that this cultivar might be a new alternative to be used under different production systems, mainly rbizantha the dry period, which represents the main constraint as far as feed availability and quality are concerned.
Decreased bite depth is commonly associated with increased time per bite, decreased bite rate Palhano et al. The data were grouped according to the season of the year as follows: As a result of its higher bracjiaria, cv.
The animals were treated with a wide spectrum vermifuge at the beginning of the experiment and with pour-on ectocide during the experiment as needed for the control of ticks and horn flies.
However, the seasonality of forage production will still be a limitation present in all scenarios Deconto,requiring new strategies to meet the animal nutritional demands for the longest period possible. O melhoramento de forrageiras tropicais no Brasil. This finding is in accordance with those described by Carvalho et al.

In February4. This finding is of great importance because the seasonality of forage production is one of the bottlenecks for pasture-raised cattle production. However, it was also believed to not limit herbage ingestion by animals because herbage accumulation was not considered in the calculation of HA. For the stratified herbage samples, the same model was applied, but the effect of the strata was added and considered fixed. Every 28 days, the cages were placed pata points representative of the average canopy height, with oiata mass and morphological composition to the areas under grazing.
Material and Methods The experiment was conducted between June and May The average daily gain observed for cv. Laboratory of Climatology, New Jersey. Based on previous analyses, the highest-order polynomial was selected. The experiment was conducted between Brachuaria and May The grazing method used was continuous stocking, with a variable stocking rate.
How to cite this article. Of these accessions, two were selected and tested for animal production: Following each harvest, the cages were placed at other points within the paddock according to the same method. However, studies on the value for cultivation and use of this new cultivar, which provide adequate and reliable information on the new genetic material to its users, are needed before it is placed on the market MAPA, Crop Breeding and Applied Biotechnology The objective of the present study was to evaluate live weight gain per animal and per area and its relationship with the characteristics of pastures of Brachiaria brizantha cv.
Grazing behaviour, herbage intake and animal performance of beef cattle heifers on marandu palisade grass subjected to intensities of continuous stocking management. Herbage allowance was not significantly different between the first two years and was higher for the third year.
Pasture samples were collected once a month, and herbage accumulation rate HARpercentage of leaves PLleaf: Nineteen selected accessions of Brachiaria brizantha were evaluated in a Regional Assay Network.

Therefore, any effort to increase the availability of quality forage during the dry season will contribute significantly to increasing cattle farming productivity. ABSTRACT The objective of the present brachiariz was to evaluate live weight gain per animal and per area and its relationship with the characteristics of pastures of Brachiaria brizantha cv.
However, except for the first dry season, because of the low herbage accumulation rate Table 2 and the small dimensions of the paddocks 0.
Before pasture establishment, soil samples were collected from the cm layer. One of the factors responsible for low beef cattle production in the tropics is inadequate animal nutrition, brachiarua mainly from the seasonality of forage production, which is characteristic of tropical regions. Hodgson suggested that herbage intake would reach its maximum at an brizzntha allowance of 10 to 12 kg of dry matter per kg of body weight. Herbage inside and outside of the cages was harvested at the ground level and sampled as described above; then, herbage mass was determined.
Live weight gain per area was calculated as the product of the average daily live weight gain of tester animals and brachiarix total number of animals tester and grazer per paddock and grazing cycle. Animals were weighed every 28 days.
A completely randomized blocks experimental design was used, with two treatments and six replicates. John Wiley, New York. Covariance structure selection in general mixed models.

Discussion The observed herbage accumulation rate variation Figures 3 A and 3B was typical bbrachiaria the tropical regions, resulting from the rainfall seasonality Figures 1 and 2 and temperature and photoperiod variations Figure 1. Three tester steers were used per paddock. Journal Range Management In spite of the adjustment of the stocking rate Table 2 and Figure 3pasture height Table 1 and herbage mass Table 4 still decreased, during that season.
